Title: Supercharging pressure regulating device
Inventor: SAKAMOTO TOSHIYUKI
IPC: F02B37/12
Filed: 1982-02-24
Abstract: PURPOSE:To obtain a small-sized and inexpensive supercharging pressure regulator  capable of setting a desired supercharging pressure relative to the number of revolutions of the engine by an arrangement wherein an actuator adapted to be actuated by  a lubricating oil pressure of an internal combustion engine introduced into a supercharger is controlled by a solenoid valve which supplies or eliminates the lubricating  oil pressure. CONSTITUTION:When a throttle valve 3 is opened to change the engine into a high  load operation, an exhaust gas turbine 11 increases its rotating speed and an air suction turbine 10 introduces supercharged air into an internal combustion engine 6 so  that the engine 6 may develop a high torque. This condition is detected by a sensor 34  for detecting the number of revolutions of the engine 6 and a sensor 35 for detecting  the pressure of the air drawn therein, and a control unit 36 deenergizes a solenoid  valve 25 for supplying a hydraulic oil pressure and a solenoid valve 26 for eliminating  it so that lubricating oil is allowed to flow into an oil pressure chamber 27 to open a  bypass valve 30. As a result, part of the exhaust gas bypasses an exhaust passage 8  and flows into an exhaust pipe 9 with the result that the number of revolutions of the  exhaust gas turbine 11 is reduced to prevent the increase in the suction air pressure. By this arrangement, the supercharging pressure can be set at a desired value relative  to the number of revolutions of the engine.

Title: Semiconductor integrated circuit
Inventor: KOGA AKIHIKO
IPC: H01L27/04
Filed: 1987-02-10
Abstract: PURPOSE:To increase dielectric strength against static electricity and the like, by making the margin of a contact part between a metal wiring and a diffusion layer neighbouring to a contact part between a metal wiring as an external terminal and a diffusion layer, large as compared with the other contact parts. CONSTITUTION:At a contact part 4, the margin 3a of the end-portion of a diffusion layer 3 is made sufficiently large, and at a contact part 7 neighboring to the above contact part also, the margin 6a of the end portion of a diffusion layer 6 is made as large as possible. Especially the margin 6a is made sufficiently large as compared with contact parts at the other parts such as internal circuits. Thereby, even if a high voltage due to electrostatic charge and the like is applied to a metal wiring 2 as an extenal terminal, the migration due to a current flowing between the diffusion layers 3 and 6 does not progress. Therefore, the short circuit between a semiconductor substrate 1 and a metal wiring 5 is prevented, and the dielectric strength is increased.

Title: Injection hole of concrete segment, and injection hole used combinedly for hanging hole and usage thereof
Inventor: FUJIKI IKUO
IPC: E21D11/00
Filed: 1995-02-20
Abstract: PURPOSE: To promote execution efficiency by opening the inside and outside of a segment to bury an embedded pipe therein, at the same time, providing a shallow recess with a diameter larger than the embedded pipe to the outside, and boring a hole in the embedded pipe, if necessary. CONSTITUTION: When grout for the backfiller of a segment is injected, an injection hole 7a is bored from the bottom of an embedded pipe 1a to a shallow guide recess 5a by means of a boring device 6a. Then, segment milk/mortar, etc., are poured from the hole 7a. Then, when a hole is not bored, since the outside of the pipe 1a is blocked with concrete, it is in a state of water seal, and no water leakage occurs. When a hole is bored, since the recess 5a is made, the thickness is relatively thin, and the recess 5a is reinforced in the circumferential edge, and damage is not spread over the outside opening. Then, when grout is injected, the recess 5a is used as guide to produce the directionality for grout injection. By the constitution, an injection port can be easily and surely formed.

Filed: 1986-02-14
Abstract: PURPOSE:To simply correct a fogged picture by converting an electric signal corresponding to a picture edge of the fogged picture into a fogged edge signal caused when the edge is fogged. CONSTITUTION:A comparator circuit 8 compares a fogged information signal (g) with information representing the size of display, switching a changeover circuit 2 depending on the result and the result of a comparison is fed to the 2nd Fourier transform circuit 9. An inverse filter forming circuit 10 receives an output signal from the 2nd Fourier transform circuit 9 and a threshold setting signal, applied prescribed processing to them and sends its output signal to a fog correction circuit 4. At the time of fog information g(x, y) takes place, a signal conversion circuit 2a converts an electric signal corresponding to the pattern edge of the fogged picture into the fogged edge signal caused when the edge is fogged. Thus, the discontinuity of picture is eliminated and corrected not giving much error as the information at the outside of boundary.

Abstract: PURPOSE:To facilitate key operations by minimizing the number of keys. CONSTITUTION:For instance, a key A is rewritten to a key Z at a key part 1. In this case, the bit data (10001100) showing the place of the key B is sent to a keyboard from an external computer. The bit data displays the place (X:2, Y:5) of the key B on the keyboard in a binary number. At the same time, the bit data (00101001) of the key Z after change is sent to the keyboard. Then a CPU incorporated to the keyboard decides from the external computer that the bit data (10001100) of the key B is out of the bit data (10000000-10011111) and then decides the place on keyboard from the bit data (10001100) for a key to be rewritten. Then the CPU writes the bit data (00101001) of the key Z sent from the external computer on the place of the key B on the keyboard.
